high pressure steam flow in the turbine .which have lots of
pressure & that pressure is used for rotating the turbine
blades. turbine , alternator & exiter are connected to the
same shaft so due to which alternator will also rotates &
elctricity generates

Answer / pillay

The steam produced by boilers is used to run a steam engine or a
turbine.To this turbine or engine is fitted a generator just like
fitted to a diesel engine.When the turbine or engine is run
electricity is produced from the generator.

Answer / ashokkumar

High pressure steam , produced by the boiler is fed to the
steam turbine blades through nozzle it tends to rotate the
turbine. In other end of the turbine generator is coupled.
when turbine rotates at the same time generator is also
start rotating. And the Electrical Energy is produced by the
generator.

Answer / a.ashraif

stream using this stream only turbine blades are rotated
and power is generated
